Trees & Towers
Felt towers, both 120 cm. The Catstronaut Starship is a rocket with a sisal ramp to scratch on the way up and a hide behind the door. The Burj Cat-lifa Tower is a spiral with a den at the floor and a perch at the top, on 40 cm of carpet. Designed by emergency vet Dr Duncan Houston.

Why this range exists
“Height is where a cat feels safe. Give her some.”
Watch where a cat goes when the vacuum comes out: up. A cat surveys from above, and an indoor cat with nothing to climb ends up on the fridge, the wardrobe or the bookshelf you did not want her on. A tower puts the high ground where you choose it, with a hide at the top or a den at the bottom, and both of ours stand 120 cm in felt so they are quiet when she lands. The one thing I ask owners to watch is the day she stops going up. An old cat who quietly gives up the top perch is not lazy; that is arthritis, and nobody notices until she stops jumping onto the bed too. A tower does not treat a joint. It shows you when one needs treating. Gary took the Burj's den on day one and the perch on day two.

Space efficiency through height rather than footprint made this ideal for our apartment living. Stability remains exceptional despite reaching impressive heights.
Height and stability allow even larger or senior cats safe exploration and lounging options. The design encourages vertical climbing behavior beautifully.
This tall tower serves as exercise equipment promoting healthy vertical activity daily. The open perch design maintains visibility throughout the home.

Both stand about 120 cm. The Burj Cat-lifa Tower is a round 40 cm footprint, so it fits a corner; the Catstronaut Starship is the rocket body plus the ramp out the front, so it wants a wall behind it and about a metre clear in front. Neither needs fixing to the wall, but both go against one. Check the ceiling only if you have a low sloping one: the top of either is 120 cm and a cat on top adds her height.
The Burj, on its own, gives two cats a place each: one in the den at the floor, one on the perch at about half height, and cats share a tower as two places rather than one bed. The Starship is one cat at a time inside the rocket, so a second cat needs a perch of her own: a Window Hammock on the glass, or a two-level house on the floor. Two high places at different heights is how you cut the squabbling in a two-cat house.
It is built to stand on its own weight with a wide base, and it goes against a wall so that a big cat launching onto the top pushes into the wall and not into the room. Do not put it where a running cat can hit it side-on. Check the clips after the first week and after any move.
The Starship does: the ramp is a wooden board faced in sisal, and every trip up is a scratch and a stretch on it. The Burj does not; felt takes claws without being a scratching surface, so it pairs with a post, and the Scratch Me Happy post stands beside the sofa arm she scratches now. Neither tower replaces a post in the room she scratches in.
A kitten takes the Starship's ramp before she can jump its height, which is the point of the ramp, and uses the Burj's den until she can make the perch at about four months. An older cat with stiff hips may not manage the ramp's slope or the perch's jump; a chair beside the tower helps, and a cat who has stopped making a jump she used to make is a vet visit before she is a new tower, because that is usually her joints.
Ignoring it in week one usually means it is in the wrong place: move it beside the window or facing the door she watches, and leave it two weeks. Do not put her on it.
